We really appreciate your review. Spread the word and share it with your friends.

The functionality of this keyboard is so beautiful. All of the keys except the space bar, are near silent and then there is the space bar. It is the most awful, annoying, difficult to use and is the only obtrusive trait of the entire keyboard! So if that clicking sound bugs you and it will trust me, skip on this.

Three stars only because of the space bar. Otherwise it would be a 5+ star rating.

Worth every penny - combined with a mouse pad and all shoulder and wrist pain is gone. This keyboard is so quiet - the favorites keys make for a quick morning. There is a zoom on the keyboard so if you can't read something on a document (like fine print), you can zoom right in! I was confused when I opened it - no directions, nothing. You have to download the Microsoft Mouse and Keyboard Center in order to learn how to operate, but once you do this, you will love it! I am a type fast and my other keyboard (wired) was so loud that my boss had to close her door. The second keyboard I bought was wireless and loud - it always hesitated which caused typos. This is a wired keyboard and I recommend it to everyone who needs an ergonomic keyboard.
